A Canadian man pretending to be pop star Justin Bieber has been arrested for allegedly sexually abusing a 12-year-old New Jersey girl online.

NJ.com reports that Essex County, NJ authorities announced Tuesday that 34-year-old Lee Moir of Toronto is being accused of forcing the young girl to perform sexual acts through an online video chat service and threatening her family. In a statement from acting Essex County Prosecutor Carolyn A. Murray, Livingston Police Chief Craig Handschuch and Toronto Police Services, authorities said that Moir will be charged in Canada for extortion, manufacturing child pornography and luring.

Moir posed as Bieber on Facebook, luring the unidentified girl to video chat with him. The Associated Press reports that authorities did not say if Moir actually used photos of Bieber to convince her that he was the pop star.

Eventually, she figured out that Moir was not Bieber, but he threatened her family if she did not continue chatting. Authorities also claim that he threatened that he would put up recordings of her on porn sites.

Moir was arrested by Canadian authorities after an officer posed as a 14-year-old girl. He set up a meeting with the officer and was arrested at the scene.

The investigation found that Moir was busy contacting other juvenile girls in the US, Canada, France, Australia and the Philippines. He used Facebook and ooVoo accounts and used several usernames.
